Abstract
There is disclosed a closely arranged file of flexible rotating disk memory elements in which a disk may be randomly accessed with minimum error and relatively rapid access time. This disk system utilizes different diameter disks which are arranged in an ascending order in a sub-stack, are rotated at a relatively slow speed. A plurality of the sub-stacks, wherein there is a correspondence between the same diameter disk of each stack, are utilized to provide for a large memory capacity. Microprocessing techniques are utilized for sub-stack and disk selection.
